Electronic height control system for a vehicle with multiple input signals

Abstract

A control system for controlling the ride height of a vehicle, the system including a controller that receives and processes multiple variable inputs to provide enhanced ride height control. The inputs include a brake system signal including an Automatic Braking System (ABS) signal and / or an Electronic Braking System (EBS) signal, a remote setpoint signal and / or a fluid dump signal. The system also provides for measuring the actual ride height, filtering the measured ride height, determining if the filter ride height signal exceeds a threshold level, and adjusting the ride height accordingly.

Description

Multi-input signal electronic height control system for vehicles technical field The present invention relates generally to vehicle suspension systems, and more particularly to electronic height control systems for controlling the ride height of vehicles. Background technique Vehicle suspension systems with mechanically linked and actuated height control valves are well known. FIG. 1 illustrates such a trailing arm suspension 10 in combination with a height control valve 12 . Trailing arm suspension 10 includes opposing trailing arm assemblies 11 mounted on opposite sides of the vehicle, preferably to vehicle frame rails 16 . Each trailing arm assembly includes a trailing arm 14 pivotally connected at one end to a suspension bracket 18 via a pivot connection 20 . The hanger bracket is suspended from the vehicle frame rails 16 . The other end of the trailing arm 14 is mounted to an air spring 22 which is attached to the frame rail 16 . The air spring 22 dampens pivoting...

Problems solved by technology

However, the system taught by Sulzyc et al. fails to meet the need to provide an electronic controller that can receive, process and act on many input signals to facilitate safe and precise adjustment of the vehicle ride height
